the measures of the interior angles of a pentagon are 2x, 6x, 4x-6, 2x-16 and 6x+2. What is the measure of the largest angle
Answered by John
Give x a number for example:

x = 1

2x = 2*1 = 2
6x = 6*1 = 6
4x-6 = 4*1-6 = -2
2x-16 = 2*1-16 = -14
6x+2 = 6*1+2 = 8

Now, which is the largest angle?
Answered by Kevin
the first thing that you need to do is solve for x. The sum of the interior angles inside a pentagon is equal to 540 degrees. you come up with the equation 2x+6x+4x-6+2x-16+6x+2=540. Then you want to simplify it down to 20x-20=540. there are multiple ways you can finish this but it turns out to be x=28. then all you do is plug in 28 for x in all of the equations of the angles and you will find that 6x+2 is the largest one at 170 degrees. I would suggest that you try it out instead of just taking the answer though. good luck!

Omg!!!! I’m 10 years ahead! Wow long time man, this is crazy!

x= 28 and the largest is 6x+2 which comes out with 170 so put
x=28
Largest= 6x+2
